 | Hey Marcos et al,
 |  
 | THanks for getting in touch.
 |  

To you

 | I am a computer music research student at Manchester Metropolitan
 | University, mainly working with Pd, SC etc.


It sounds very interesting, since Musix was made thinking about 
education... so, I am glad

 | I have been asked by 
 | the Uni to put together some cutting edge tools, to take into
 | schools, trying to get 13-15 year olds interested in Linux and the
 | whole host of amazing apps that are taking over from the need to
 | run Cubase etc... 

Great!

14-15 years old childs go to the Manchester Metropolitan University?

 | WE are going into a couple of different schools with widely
 | different equipment in each.  Musix seems to me to be the best all
 | round distro, that works on the most machines and containing the
 | widest selection of apps.  Its a really good job so well done to
 | you all! 

Thanks, this is going to musix-colaborad at lists.ourproject.org, part of 
the team

 | Back to my problems...
 |  
 | Still no joy with firewire/freebob. (Can I add that I am a recent
 | convert to Linux, so please be patient with my noobness:) 

Dont worry

 | Here is Jacks take on loading the freebob driver:
 | root at 0[root]# jackd -dfreebob
 | jackd 0.109.2
 | Copyright 2001-2005 Paul Davis and others.
 | jackd comes with ABSOLUTELY NO WARRANTY
 | This is free software, and you are welcome to redistribute it
 | under certain conditions; see the file COPYING for details
 |
 | JACK compiled with System V SHM support.
 | loading driver ..
 | Freebob using Firewire port 0, node -1
 | Ieee1394Service::initialize: Could not get 1394 handle: No such
 | file or directory Is ieee1394 and raw1394 driver loaded?

Hey!

You must load the driver (module) that jack is asking for, as root 
user type:

modprobe raw1394
modprobe ieee1394

If you want them to load at each boot, just add them to

/etc/modules-2.6.21


How did I found this drivers?

I just log as root into a konsole (sudo -i), then I wrote:

iee 

and pressed TAB, it will show you all the iee* files:

ieee1394              ieee80211_crypt       ieee80211_crypt_tkip  
ieee80211softmac
ieee80211             ieee80211_crypt_ccmp  ieee80211_crypt_wep


the same with raw...

So: that should be your solution, 

I would like to see photos of students using GNU/Linux at the 
Manchester Metropolitan University


keep in touch!

Regards :D

 | Many thanks for the help so far.

 | All good wishes,

 |
 | ufff
 |

 | Musix recent version is 1.0 R4 dvd, r2 is too old, but the problem

 |
 | Could you tell us how do you launch jack?
 |
 | messages?
 |
 |
 | About the distorted sound on the onboard sound card,try

 | Thanks
